## Cost calculation

The cost of using Yandex.Mail for Business depends on the number of users in the company. This number may change throughout the month. To factor in the change, the cost of using Mail is calculated daily. The monthly cost of services is the result of adding up the cost for all days in the month.

The cost of using Mail per day is calculated using the formula:

``Cost per day = ₽100 / Number of days per month × Number of users``

When calculating the number of users on a particular day, the total number of unique users in the company on that day is taken into account.

As an example, let's say the company had 10 users at the beginning of the day. You deactivated 2 of them and activated 3 new ones. The total number of unique users in the company on this day is 13. You are charged for 13 users on this day.

Example of calculating the monthly cost of Yandex.Mail for Business:

Let's say the number of company employees in January changed like this:

1. 14 days with 9 employees
2. 17 days with 15 employees

In January, the daily price of Mail use per employee is:

``100 / 31 = 3,23 ₽``

As the number of employees changed, the price of Mail use in January is:

``3,23 × (14 × 9 + 17 × 15) =  1230 ₽``
